Squeaking front axle

[txarkitekt]

If i replace one u-joint, should i replace just the one, both on front axle, or all 4?

I would suggest spraying some kind of lubricant on one U-joint at a time and driving it. Once it stops after you spray the last one--replace that exact one--not all 4.

i already told him about the muffler bearing Tyler, so you fail!!!

You must have made the post and erased it before anyone saw it. Because otherwise--YOU FAIL.
